Our factory workshop
1. Input:100-240Vac 50/60Hz
2. Input voltage range: 90-264Vac
3. Input plug(power cord): EU US UK AUS South Korea Plugs(or Interchangeable plugs)
1. Max voltage (with no load): 13-15V(for 2.4-6V 800mA), 19-22V(for 6-10V 600mA)
3.6-6V 800mA(for 3-5cells nimh battery pack)
4.8-9.6V 800mA(for 4-8cells nimh battery pack)
6-12V 600mA(for 5-10cells nimh battery pack)
3. Trickle Current: 55--65MA(Pulse ratio 1/20 +10mA)
4. Short Circuit Current: 10—20mA
5.Suitable Chargin Voltage: By -deltaV,it can find suitable charging voltage for charging batteries.
Such as 4cells Ni-mh battery,charging voltage will set to be 6V,trickle current: 45-65mA
1. -delta VDetect: -5mV
2. 0 delta V Detect: 50--65S
3. Temperature protect: Power Supplier IC = 150°C
4. Temperature protect(optional): Battery package 50--60°C
Using 10K MF52 NTC, B=3950
5.Pulse ratio: 35/512 512mS/Cycle
(Trickle Charging Mode, each charging time:512mS, stop time:35mS)
6.Timer:2.5-8Hours (Suitable for batteries with capacity 1.2-4.4AH)
1. Over-Current Protection
2. Short-circuit Protection
3. Polarity Reverse Protection
4. Over-temeprature protection
5. Over-load Protection
Led display for charge state:
1. Green---no load/ fully charged
2. Red---in Charging
3. Red flashes---Output polarity reverse/ Short-circuit/ low Battery voltage
The battery is charging 500mS and stop 35mS.
That makes the charging progress most effectively and battery package’s temperature rising lower.
